Description

   Bathroom dryer   

The present invention relates to a bathroom dryer provided in a bathroom and having a filter in an air passage.

Conventionally, in a bathroom dryer, a filter has been used in order to prevent inhalation of dust inside the product. Furthermore, in the bathroom dryer, the filter maintenance signal for prompting the user to maintain the filter is displayed at a stage where the filter has been operated for a fixed period of time. The bathroom dryer has a heating function for heating the bathroom, a drying function for making the air in the bathroom dry, and a ventilation function for ventilating the bathroom air. It also includes a 24-hour ventilation function corresponding to the building standard method.

Since the Building Standards Act stipulates the obligation of 24-hour ventilation operation, regardless of the strength of the fan, the maintenance signal based on the accumulated time of the operation time of the fan used in the 24-hour ventilation operation in the weak operation mode is taken as the reference. display. However, in single-family houses, there are also cases where individual ventilation in each room or other ventilation methods in the whole hall of the heat exchange type are used, and the 24-hour ventilation operation may not be used. Therefore, in the bathroom dryer, regardless of the strength of the fan, the accumulated time of using the power-on time in the display of the maintenance signal is also reviewed.

Patent Literature 1 discloses a bathroom ventilation dryer. The bathroom ventilation dryer adopts the following structure. When the detection circuit detects the power supply, it accumulates the power-on time by the accumulation means, and periodically resets the power supply time. The accumulated power-on time is written and memorized in the memory means, and the user is notified of the power-on time memorized by the memory means. If the bathroom ventilator according to Patent Document 1 is used, the user can grasp the use time according to the accumulated energized time to the control substrate, confirm the use status of the product, and perform appropriate maintenance, thereby preventing the occurrence of smoke. .

On the other hand, filters have different pollution conditions due to the difference in air volume caused by the strength of the fan when using a bathroom ventilator. That is, the filter has different pollution conditions according to the use conditions of the user's bathroom ventilation dryer.

[Patent Document 1] Japanese Patent Laid-Open No. 2010-121788

However, when the filter is to be maintained in accordance with the technique of Patent Document 1, the difference in air volume caused by the strength of the fan is not taken into consideration, and a maintenance signal is displayed regardless of the degree of pollution of the filter.

Furthermore, depending on the method of use, there may be a problem that the actual display period of the maintenance signal may be delayed from the appropriate display period of the maintenance signal. In addition, the user performs maintenance of the filter after the appropriate maintenance period is exceeded. The delay in the maintenance period is considered to be a cause of insufficient heating performance accompanied by a decrease in air volume, or failure of a product.

The present invention has been developed in view of the above, and an object thereof is to obtain a bathroom dryer that can notify a maintenance signal of a filter at an appropriate time corresponding to a use condition of a user.

In order to solve the above-mentioned problems and achieve an object, the bathroom dryer of the present invention includes a main body, which is fixed to the ceiling of the bathroom, and a control switch, which has a display portion and is connected to the main body. The body includes: a blower, which sucks the air from the bathroom into the body and generates airflow to the body; a filter, which is installed on the inflow side of the air of the blower; a power-on time measurement section, which measures the body from an external power source. The power-on time; the running time measurement section measures the running time of the blower. In addition, the system includes: an accumulating unit that accumulates the energized time measured by the energizing time measuring unit to calculate the accumulated energized time, and calculates the accumulated operating time by accumulating the operating time measured by the operating time measuring unit; and notification The control unit controls the purpose of displaying that the cleaning time of the filter is reached when at least one of the accumulated operation time and the accumulated power-on time accumulated by the accumulation unit reaches a predetermined reference condition. According to the operation mode of the blower, the accumulation unit accumulates more operation time in the case of an operation mode with a relatively large amount of ground air than in the case of an operation mode with a relatively small amount of ground air.

The bathroom dryer of the present invention has the effect of notifying the maintenance signal of the filter at an appropriate time corresponding to the use conditions of the user.

In addition, the bathroom dryer 100 includes a heater 4 for heating the circulating air blown from the circulating air outlet 8 after passing through the first air passage, and a filter 6 for removing the air inhaled by the Silok fan 2 dust. The heater 4 is disposed above the circulation air outlet 8 inside the main body casing 1. The filter 6 is arranged between the Silo fan 2 and the air inlet 10 on the inflow side of the Silo fan 2.

The lower side of the bathroom dryer 100 on the side of the bathroom 52 is covered by the design panel 11. A circulation blowout port 12 is provided below the circulation blowout port 8 in the design panel 11 to blow the air blown out from the circulation blowout port 8 into the bathroom 52.

On the upper side of the fan motor 7, components related to the control and power supply of the bathroom dryer 100 are arranged on the control board 9. Fig. 4 is a diagram showing a functional configuration of a bathroom dryer 100 according to the first embodiment of the present invention.

The bathroom dryer 100 includes a power source unit 31 as a component related to a power source. The power source unit 31 is connected to a commercial AC power source which is an external power source 54 via a power source line 56. The power source unit 31 is an AC power source supplied from an external power source 54 via a circuit breaker 55, generates control power for operating the constituent parts of the bathroom dryer 100, and supplies the control power to each part of the body 21 of the bathroom dryer 100. . In addition, in FIG. 4, illustration of the power supply line connecting the power supply part 31 and one part of each component is abbreviate | omitted.

The bathroom dryer 100 is a component related to the control of the bathroom dryer 100, and includes a power-on time measuring unit 32 for measuring the power-on time for applying power to the body 21, and a first control unit 33 for performing the entire bathroom dryer 100. The control section of the control; the running time measurement section 34 measures the actual running time of the Siloco fan 2; and the accumulation section 35 accumulates the measured values in the energization time measurement section 32 to calculate the accumulated energization time, and accumulates The measured value in the operating time measurement unit 34 calculates the cumulative operating time.

The bathroom dryer 100 is a component related to the control of the bathroom dryer 100, and includes a first memory unit 36 that stores the accumulated power-on time and accumulated operation time accumulated by the accumulation unit 35; the notification unit 37, which Control for displaying the filter maintenance signal based on the accumulated power-on time and accumulated operating time memorized by the first storage unit 36; and the first communication unit 38 performs bidirectional communication with the second communication unit 41 of the control switch 22. communication.

The first control unit 33 performs overall control in the bathroom dryer 100 including control of the operation of the Silo fan 2. The first control unit 33 controls the Silok fan 2 based on the instruction information of the operation of the bathroom dryer 100 transmitted from the control switch 22.

The energization time measurement unit 32 measures the energization time when the power of the bathroom dryer 100 is turned on and the main body 21 of the bathroom dryer 100 is energized from the external power source 54, that is, the energization time for energizing the first control unit 33, and the accumulation unit 35 teleport. The energization time measurement unit 32 transmits the energization time to the accumulation unit 35 at a predetermined cycle while the first control unit 33 is energized. The state where the power of the bathroom dryer 100 is turned on is the state where the circuit breaker 55 is turned on.

The energization time measurement unit 32 can be configured by combining a voltmeter and a time meter. The voltmeter detects the energization of the body 21 of the bathroom dryer 100, that is, the energization of the first control unit 33, and the time measurement unit can measure. The time when the voltmeter is energized to the bathroom dryer 100 is detected. In the energization time measurement unit 32, a general timer for energization time measurement may be used. The time measuring device uses the built-in timer function or timer device of the microcomputer. The configuration of the conduction time measurement unit 32 is not limited to the configuration described above.

The operation time measurement unit 34 measures the actual actual operation time of the Silo fan 2 and transmits it to the accumulation unit 35. The operation time measurement unit 34 periodically transmits the actual operation time to the accumulation unit 35 at a predetermined cycle during the operation of the Silo fan 2.

The operation time measurement unit 34 can measure the actual operation time of the Siloco fan 2 by acquiring the operation control information of the Siloco fan 2 from the first control unit 33. The operation control information of the Silo fan 2 includes, for example, the start time of the Silo fan 2, the end time of the Silo fan 2, and the operation mode of the Silo fan 2. The start time of the operation of the Silo fan 2 is obtained based on the start time of the operation control of the Silo fan 2 in the first control unit 33. The end time of operation of the silo fan 2 is obtained based on the end time of the operation control of the silo fan 2 in the first control unit 33.

Also, similar to the energization time measurement unit 32, it can also be measured by a voltmeter that detects the energization of the Silok fan 2 and a time measuring device that can measure the time of energization of the Silok fan 2 by a measurable voltmeter. Actual running time of Silok fan 2.

The accumulation unit 35 accumulates the energization time measured by the energization time measurement unit 32, calculates the accumulated energization time, and then transmits the accumulated energization time to the first storage unit 36 to be memorized. In addition, the accumulation unit 35 weights and accumulates the actual operation time measured by the operation time measurement unit 34 in accordance with the operation mode of the Siloco fan 2, and calculates the accumulated operation time, and transmits the accumulated operation time to the first memory unit 36 and Make memories. The accumulation unit 35 transmits and accumulates the accumulated accumulated operation time to the first memory unit 36 at a predetermined period during the operation of the Silo fan 2. The accumulation unit 35 reads the latest accumulated power-on time and accumulated operation time stored in the first storage unit 36 for the next accumulation process. In addition, the accumulation unit 35 may cause the first storage unit 36 to memorize the accumulated accumulated power-on time and accumulated accumulated operation time, and keep the latest accumulated power-on time and accumulated operation time for the next accumulated processing.

The accumulation unit 35 weights the accumulated operation time according to the intensity of the operation mode of the Siloco fan 2, and is different from the method of accumulation of the operation time measured by the operation time measurement unit 34. That is, the accumulation unit 35 is an accumulation of the operation time measured by the operation time measurement unit 34. In the case of an operation mode with a relatively large amount of ground air, it is more appropriate to add the operation time to the operation mode with a smaller amount of ground air. If the operation time is too large, the operation time is accumulated. The accumulation unit 35 can determine the operation mode of the Siloco fan 2 by acquiring instruction information of the operation of the bathroom dryer 100 held by the first control unit 33.

In the case where the operation mode of the Silo fan 2 is the operation mode with the least amount of air, the accumulation unit 35 directly adds the actual operation time measured by the operation time measurement unit 34 to the accumulated operation time to accumulate the operation time.

On the other hand, the accumulation unit 35 is a case where the operation mode of the Silo fan 2 is another operation mode in which the air volume is greater than the weak operation mode. Based on the air volume of the Silo fan 2 in the weak operation mode and other operation modes Compared with the actual operation time, the operation time is added and the operation time is accumulated. That is, the accumulation unit 35 is a case where the operation mode of the Silok fan 2 is another operation mode in which the air volume is greater than the weak operation mode. The actual operation time is added to the Silok fan based on the weak operation mode and other operation modes. The air volume ratio of 2 is the additional operation time determined, and the operation time is accumulated.

Fig. 5 is a diagram showing the conditions for the cumulative processing in the bath dryer 100 according to the first embodiment of the present invention. In FIG. 5, the air volume ratio of the case where the operation intensity of the Silo fan 2 during the operation of the bathroom dryer 100 is a strong operation mode to the case where the operation volume is a weak operation mode is twice the air volume ratio. The presence or absence of the cumulative time of the filter is classified and displayed. Here, the cumulative operating time of the Siloco fan 2 which is accumulated by weighting the operating time of the Siloco fan 2 according to the intensity of the operating mode of the Siloco fan 2 is referred to as a filter cumulative time. In addition, if the air volume in the case of strong operation of the Siloco fan 2 is regarded as a large air volume and the air volume in the case of a weak operation is regarded as a small air volume, the large air volume is twice the air volume of the small air volume. The conditions for the accumulation processing shown in FIG. 5 are determined in advance and memorized by the accumulation unit 35.

The operating time measurement section 34 measures the operating time of the Siloco fan 2 only when the Siloco fan 2 of the wind passes the filter 6 and transmits it to the accumulation unit 35. That is, the operation time measurement unit 34 does not perform measurement of the operation time of the Silo fan 2 even when the bathroom dryer 100 is on and the operation is stopped and the operation is stopped.

Therefore, the accumulation unit 35 accumulates the accumulated time of the filter only when the Silok fan 2 of the wind passes the filter 6 is operated. Moreover, even if the power of the bathroom dryer 100 is on, the accumulation unit 35 does not perform accumulation of the filter accumulation time in the standby state and when the operation is stopped.

In addition, the accumulation unit 35 is a case where the operation mode of the Silo fan 2 is the strong operation mode, and a time that is twice the actual operating time of the actual operation time of the Silo fan 2 is used as the filter accumulated time. Accumulate, and let the 1st memory | storage part 36 memorize. That is, the accumulation unit 35 is a case where the air volume supplied by the Siloco fan 2 is a large air volume, and the time that is twice the actual operating time of the Siloco fan 2 is regarded as the cumulative time of the filter. Grand total. In the case where the operation mode of the Silo fan 2 is the strong operation mode, the amount of wind passing through the filter 6 is more than that in the weak operation mode, and the filter 6 is liable to become dirty. Therefore, the operating time accumulated in the filter accumulated time is weighted and the added operating time is increased.

On the other hand, the accumulation unit 35 is in a case where the operation mode of the Siloco fan 2 is a weak operation mode, and the actual operation time of the Siloco fan 2 is directly accumulated to the filter accumulated time, and the first memory unit 36 is memorized. That is, the accumulation unit 35 is a case where the amount of air supplied by the Silo fan 2 is a small air volume, and the actual operation time of the Silo fan 2 is directly accumulated for the filter accumulated time.

In addition, the energization time measurement unit 32 is in a state where the power of the bathroom dryer 100 is turned on and the bathroom dryer 100 is energized, that is, in a state where the first control unit 33 is energized, the energization time is always measured, and the accumulation unit is measured. 35 teleport. The accumulation unit 35 does not perform weighting according to the operation mode of the Siloco fan 2 during the accumulated time of power-on. Therefore, the accumulation unit 35 directly accumulates the time when the power of the bathroom dryer 100 is turned on and the bathroom dryer 100 is energized as the accumulated time for energization.

When the operation mode of the Silo fan 2 is another operation mode in which the air volume is greater than the weak operation mode, the operation time measured by the operation time measurement unit 34 may be added from the setting set by the control switch 22. Run time and accumulate accumulated running time.

In the state where the power of the bathroom dryer 100 is turned off, neither the energization time measurement unit 32 nor the operation time measurement unit 34 measures, and therefore, the accumulation unit 35 does not perform the accumulation processing of the accumulated energization time and the filter accumulation time. The state where the power of the bathroom dryer 100 is turned off is the state where the circuit breaker 55 is turned off. In addition, the cumulative method of the filter cumulative time shown in FIG. 5 is an example. More operation modes can be set, and the method of weighting the operating time when the cumulative filter cumulative time can be changed.

The first storage unit 36 stores the accumulated power-on time and the accumulated operating time transmitted from the accumulation unit 35. The first memory unit 36 is a case where the bathroom dryer 100 is powered on and off. In order to prevent the stored information from being erased, a nonvolatile memory device is used.

The notification unit 37 performs a cleaning period when the display unit 43 of the control switch 22 to be described later is displayed when at least one of the accumulated power-on time or accumulated operation time accumulated by the accumulation unit 35 reaches a predetermined reference condition. Control of the filter maintenance signal to be notified.

The notification unit 37 is a condition for determining whether or not the filter 6 needs to be maintained from the use time of the Silo fan 2, and the following first condition is used. The first condition is "the cumulative operating time of the Siloco fan 2 is the cumulative time A or more of the predetermined first reference time". The first reference time is a threshold value of a cumulative operating time for determining whether or not the filter 6 needs to be maintained from the use time of the Silo fan 2.

In addition, the notification unit 37 is a low frequency of use of the Silo fan 2. However, since the power-on time to the main body 21 is long and a fixed period has passed from the installation of the bathroom dryer 100, it is a condition for determining whether the filter 6 needs to be maintained Use the second condition below. The second condition is "The cumulative operating time of Silok fan 2 is less than the cumulative time A of the predetermined first reference time, but it is greater than the cumulative time B of the predetermined second reference time which is shorter than the first reference time. And the accumulated power-on time is the accumulated time C or more of the predetermined third reference time. " The second reference time is a low frequency of use of the Siloco fan 2, but when the main body 21 is energized for a long time, it becomes a threshold value of the accumulated cumulative operating time for determining whether or not the filter 6 needs to be maintained. The third reference time is that the frequency of use of the Silok fan 2 is low, but when the power-on time of the main body 21 is long, it becomes a threshold value of the cumulative power-on time of the reference for determining whether the filter 6 needs to be maintained. In addition, the "case where the use frequency of the Silo fan 2 is low, but the power-on time to the body 21 is long," also includes "the case where the power-on time to the body 21 is long, but the bathroom dryer 100 is not operated even once." . That is, the "case where the frequency of use of the Silo fan 2 is low" also includes the case where the above-mentioned accumulated time B is 0.

That is, the notification unit 37 controls the display unit 43 to display the filter maintenance signal when the cumulative operation time of the Silo fan 2 is equal to or more than the predetermined first reference time. In addition, the notification unit 37 is that the accumulated operating time of the fan 2 in Silok is less than the predetermined first reference time, but it is longer than the predetermined second reference time that is shorter than the first reference time, and the accumulated power-on time is the predetermined second reference time. In the case of 3 or more reference times, control is performed such that the display unit 43 displays the filter maintenance signal.

The notification unit 37 uses the two conditions described above to determine whether the filter 6 needs to be maintained. By this, the filter maintenance signal can be surely turned on, for example, 6 months after the start of use, and the user can be encouraged to regularly maintain the filter.器 6。 Six.

The processor and the memory system for realizing the second communication unit 41 may be the same as the processor and the memory for realizing the second control unit 45, or may be different processors and memories.

When the bathroom dryer 100 is disposed on the ceiling surface 53 of the bathroom 52, as shown in FIG. 2, the body case 1 is inserted into an opening (not shown) provided in the ceiling surface 53 of the bathroom 52 from the bathroom 52 side, and The flange 1 a provided on the outer periphery of the lower surface of the main body case 1 is pressed against the ceiling surface 53, and is thereby arranged parallel to the ceiling surface 53. Then, the flange 1 a is fastened to the ceiling surface 53 of the bathroom 52 with screws, whereby the body case 1 is fixed to the ceiling surface 53. Next, the exhaust port 5 is connected to an exhaust duct 51 provided on the rear surface of the ceiling. The control board 9 is connected to a control switch 22 provided on the wall of the undressing room via a communication line 23.

Next, the display operation of the filter maintenance signal in the bathroom dryer 100 will be described. Fig. 8 is a flowchart showing a procedure of a filter maintenance signal display operation of the bathroom dryer 100 according to the first embodiment of the present invention.

First, when the power of the bathroom dryer 100 is turned on, and when the energization from the external power source 54 to the main body 21 is started, the energization time measurement unit 32 measures the energization time and periodically transmits it to the accumulation unit 35. The operation time measurement unit 34 measures the operation time of the Silo fan 2 and periodically transmits the operation time to the accumulation unit 35.

Next, in step S10, the accumulation unit 35 obtains the accumulated energization time stored in the first storage unit 36, accumulates the energization time transmitted from the energization time measurement unit 32, and calculates the latest accumulated energization time. In addition, the accumulation unit 35 obtains the accumulated filter time stored in the first storage unit 36 and accumulates the operation time transmitted from the operation time measurement unit 34 to calculate the latest filter accumulated time. As described above, the accumulation unit 35 performs weighting on the operation time measured by the operation time measurement unit 34 in accordance with the operation mode of the Siloco fan 2 and accumulates the filter accumulated time.

Next, in step S20, the notification unit 37 uses the above-mentioned first condition to determine whether or not the filter 6 needs to be maintained from the use time of the Silo fan 2. That is, the notification unit 37 determines whether or not the accumulated time of the filter of the Silo fan 2 is equal to or greater than the accumulated time A of the predetermined first reference time.

When the filter accumulated time is equal to or greater than the accumulated time A, that is, when the step S20 is Yes, the notification section 37 issues an instruction to cause the display section 43 of the control switch 22 to display the filter maintenance signal in step S30. The display unit 43 lights the filter maintenance signal.

In the case where the filter accumulated time is not more than the accumulated time A, that is, when the step S20 is No, the notification unit 37 uses the second condition described above. Although the frequency of the use of the Silo fan 2 is low, The power-on time is long, and since the fixed period has elapsed from the installation of the bathroom dryer 100, it is determined whether the filter 6 needs to be maintained. That is, the notification unit 37 determines in step S40 whether "the cumulative time of the filter of the Siloco fan 2 is equal to or greater than the cumulative time B of the predetermined second reference time, and the cumulative power-on time is cumulative of the predetermined third reference time Time C or more ".

In the case where the condition "the filter cumulative time is greater than the cumulative time B and the cumulative power-on time is greater than the cumulative time C of the predetermined third reference time" is not satisfied, that is, when the step S40 is No, the notification unit 37 is Return to step S10.

In the case where the condition that "the accumulated time of the filter is equal to or greater than the accumulated time B, and the accumulated power-on time is equal to or greater than the accumulated time C of the predetermined third reference time" is satisfied, that is, the case where Yes in step S40 is in step S30 The notification unit 37 issues an instruction to display the filter maintenance signal on the display unit 43 of the control switch 22. The display section 43 lights the filter maintenance signal.

Next, a description will be given of a method of integrating the filter integration time in the integration unit 35 in step S10 described above. FIG. 9 is a flowchart showing a procedure of a method for integrating the filter accumulated time in the accumulation unit 35 of the bathroom dryer 100 according to the first embodiment of the present invention.

In step S110, the accumulation unit 35 determines whether the operation mode of the Silo fan 2 is a weak operation mode.

In the case where the operation mode of the Silo fan 2 is the weak operation mode, that is, when the step S110 is Yes, the step S120 is performed, and the accumulation section 35 directly performs the accumulated time of the filter obtained from the first memory section 36. The running time transmitted from the running time measurement unit 34 is accumulated to calculate the latest filter accumulated time.

When the operation mode of the Silo fan 2 is not the weak operation mode, that is, when the step S110 is No, the operation mode of the Silo fan 2 is a strong operation mode that is stronger than the weak operation mode, and passes the filter 6 The air volume of the wind is more than that in the weak operation mode, and the filter 6 is easily dirty. Therefore, in step S130, the accumulation unit 35 calculates the latest filter accumulation time by accumulating the filter accumulation time obtained from the first memory unit 36 and the time that is twice the operating time transmitted from the operation time measurement unit 34. time.

By performing the above processing, the accumulation unit 35 can accumulate the filter accumulated time by weighting the operation time measured by the operation time measurement unit 34 according to the operation mode of the Siloco fan 2.

The bathroom dryer 100 performs the above processing, so that the display unit 43 can display the filter maintenance signal.

The conditions of the first reference time, the second reference time, and the third reference time that are the threshold values for the case where the filter maintenance signal is displayed can be easily changed by changing only the program for realizing the function of the notification section 37. . The conditions of the first reference time, the second reference time, and the third reference time can be easily changed from the control switch 22. Thereby, the display time of the filter maintenance signal can be easily changed to an arbitrary time in accordance with the use environment and family structure of the bathroom dryer 100.

For example, the initial setting assumes a weak operation mode of 24-hour ventilation, and adopts a time point at which the cumulative operation time of the Siloco fan 2 becomes 6 months or more to make the filter maintenance signal light. That is, the initial setting of the first reference time is regarded as 6 months. In addition, by using 6 months as the maximum value of the set time of the first reference time, it is possible to prevent a decrease in the function caused by a decrease in the air volume and a product failure.

When components are replaced when the bathroom dryer 100 fails, the accumulated time stored in the control board 9 or the control switch 22 of the bathroom dryer 100 is compared, and the data with more accumulated time is written on the less data. Accumulation of accumulated time can continue to be better.

When the bathroom dryer 100 malfunctions, one of the accumulated time stored in the first storage unit 36 of the bathroom dryer 100 and the accumulated time stored in the second storage unit 44 of the control switch 22 is not correct. Value situation. In this case, the accumulated time stored in the first storage unit 36 of the bathroom dryer 100 and the accumulated time stored in the second storage unit 44 of the control switch 22 is considered to be correct. , And write on the less accumulated time. Thereby, the accumulated time stored in the first storage unit 36 and the accumulated time stored in the second storage unit 44 are synchronized to the correct same value, and the accumulation of the accumulated time can be continued.

Further, for example, even if the accumulated time stored in the first storage unit 36 and the accumulated time stored in the second storage unit 44 deviate from the correct values, the first storage unit 36 and the second storage unit 44 can be made to be different. The accumulated time of memory is corrected to be closer to the correct value.

When the product body of the bathroom dryer 100 or the control substrate 9 is replaced due to a failure, the accumulated time stored in the second memory portion 44 of the control switch 22 is written into the first memory portion 36 of the body 21, so that the accumulated time can be accumulated. The accumulation of time continues. Thereby, the accumulated time stored in the first storage unit 36 and the accumulated time stored in the second storage unit 44 are synchronized to the correct same value stored in the first storage unit 36, so that the accumulation of the accumulated time can be continued.

On the other hand, in the case where the control switch 22 is replaced due to a failure, the second storage unit 44 of the control switch 22 after the replacement can store the accumulated time stored in the first storage unit 36 of the main body 21, so that the accumulated time can be made. The accumulation continues. Thereby, the accumulated time stored in the first storage unit 36 and the accumulated time stored in the second storage unit 44 are synchronized with the correct same value stored in the first storage unit 36, and the accumulation of the accumulated time can be continued.

The above-mentioned bathroom dryer 100 of the first embodiment, the accumulation unit 35 weights the actual operation time of the Siloco fan 2 according to the operation mode of the Siloco fan 2, and calculates the cumulative operation of the Siloco fan 2. time. In addition, the notification unit 37 performs control to display the filter maintenance signal on the display unit 43 when the cumulative operation time is equal to or longer than the first reference time. With this, the bathroom dryer 100 can notify the filter maintenance signal at an appropriate time corresponding to the use form of the bathroom dryer 100 by the user.

In addition, the bathroom dryer 100 is a cumulative unit 35 that accumulates the energized time to the body 21 to calculate the accumulated energized time. In addition, the notification unit 37 may be less than the predetermined first reference time when the cumulative operation time is less than the predetermined second reference time, which is shorter than the first reference time. Control is performed such that the display unit 43 displays a filter maintenance signal. With this, the bathroom dryer 100 can notify the filter maintenance signal at an appropriate time corresponding to the use form of the bathroom dryer 100 by the user.

In this way, because the bathroom dryer 100 can prompt the user to clean the filter 6 at an appropriate time, the failure of the bathroom dryer 100 caused by the blocking of the filter 6 can be prevented, and the blocking of the filter 6 can be prevented. The reduction in performance is minimized. In addition, it is possible to minimize the decrease in heating performance accompanying the decrease in the amount of blown air to the bathroom 52 caused by the clogging of the filter 6. In addition, it is possible to suppress an abnormal stop caused by a rise in the temperature of the heater caused by a decrease in the amount of blowing air to the bathroom 52 caused by the clogging of the filter 6. In addition, it is possible to suppress the execution of the thermostat function due to the increase in the temperature of the heater caused by the decrease in the amount of blowing air to the bathroom 52 caused by the clogging of the filter 6.

In addition, the bathroom dryer 100 is in a state of being powered only without being operated, and does not notify the user of unnecessary filter maintenance signals. That is, in the above step S40, "the cumulative time of the filter of the Siloco fan 2 is equal to or greater than the cumulative time B of the second reference time, and the cumulative power-on time is equal to or greater than the cumulative time C of the predetermined third reference time" The conditions include the case where the accumulated time B is 0, and the "case where the power-on time to the main body 21 is long, but the bathroom dryer 100 is not operated even once." In this case, it is of course not necessary to clean the filter 6. Moreover, the user also considers that the filter 6 is not required to be cleaned. Therefore, in this case, by not notifying the user of the filter maintenance signal, it is possible to avoid the situation where the user is notified of the filter maintenance signal due to violation of the determination that the filter 6 is not yet required to be cleaned and the user is confused.

In addition, the bathroom dryer 100 is a program for realizing the functions of the accumulation unit 35 and the notification unit 37 only by adding a general bathroom dryer to the functions of the accumulation unit 35 and the notification unit 37, which can reduce the cost of products. Under the influence of this, notify the filter maintenance signal at an appropriate time.

Therefore, according to the bathroom dryer 100, the operation mode and use environment of the Siloco fan 2 can be matched, and the filter maintenance signal can be notified at an appropriate period corresponding to the user's use conditions, which can prompt the user to clean.

The configuration shown in the above embodiment is an example showing the gist of the present invention, and may be combined with other well-known technologies, and a part of the configuration may be omitted or changed without departing from the gist of the present invention.
